I'm not sure if this has been posted somewhere before, but I can't find anything that really addresses this type of a problem. For college we need to design an amplifier circuit using a transistor, this is not that bad. The problem is that there is no proper explanation that I can find of where to start doing this given the specifications. I will post the question here. I'm not asking someone to solve it, but rather just to show me what resistor would affect what property of the circuit, and how to go about this design. Equations would also help a lot. Here is the question:
Design a small-signal AC gain stages (CE configuration) using both a BJT. Aim for the following requirements:
- Operate from a single power supply voltage
- Be suitable for either voice (300 Hz - 3 kHz) or music (100 Hz - 20 kHz) amplification
- Provide a gain of 50, and
- Drive a load of 5 kΩ (this has to be included explicitly in your circuit).
We are going with voltage divider biasing for the circuit.
